Megalodon
Otodus megalodon (Megalodon · メガロドン)
Known only from fossils. The IUCN Red List assesses only species extant since 1500 CE, so fossil taxa are not assigned a category.

📖 1. Overview
With a body length of 16 m and a maximum bite force of 180,000 N, this gigantic carnivorous shark had the most powerful bite in Earth's history.
🌐 Wikipedia Summary ExtractOtodus megalodon, commonly known as megalodon, is an extinct species of giant mackerel shark that lived approximately 23 to 3.58 million years ago (Mya), from the Early Miocene to the Early Pliocene epochs. This prehistoric fish was once thought to be a member of the family Lamnidae and a close relative of the great white shark, but has been reclassified into the extinct family Otodontidae, which diverged from the great white shark during the Early Cretaceous.
